Innovative Design

Unprecedented gaming horsepower. Exceptional craftsmanship. A 7-phase dualFET power supply. All cooled by a radial fan with an advanced vapor chamber designed to for consistent performance in even the most thermally challenging environments. This is the forward-thinking innovation that makes the GeForce® GTX 1080 Ti the Ultimate GeForce.

ULTIMATE COOLING

Next-Gen DirectCU H2O Hybrid Cooling

Complete flexibility with your choice of air or liquid cooling

Next-Gen DirectCU H2O is a hybrid thermal solution that combines a vapor chamber and water channel. Compared to the previous-gen design, the DirectCU H2O's in-channel water-flow rate has been increased by 22% for better heat dissipation. The new ROG Poseidon is constructed with a larger 2.5-slot cooler, providing 40% more surface area for thermal dissipation compared to previous 2-slot designs, leading to lower temperatures and quieter performance.

Standard G1/4-Inch Terminal Block

With a new G1/4-inch terminal block*, the Poseidon allows you to choose from a wide variety of fittings and makes plumbing a custom water loop easier than ever.* Barbs need to be purchased separately.

Make the Cooling Even More

The ROG Poseidon features our patented wing-blade design fans that provide maximum airflow. With IP5X certification, the fan bearings are protected from dust ingress, ensuring a long lifespan. Armed with an efficient cooler and 0dB fan technology, the ROG Poseidon allows you to play light gaming sessions in complete silence and has the credentials to tackle heavier workloads with minimal noise.

Patented Wing-Blade Design

Max Air Flow with 105% More Air Pressure

Patented wing-blade fans deliver maximum air flow and 105% greater static pressure over the heat sink, while operating at an up to 3X quieter volume than reference cards.

ASUS FanConnect II features two 4-pin, hybrid-controlled headers that can be connected to both PWM and DC system fans for optimal system cooling. The connected fans reference both the GPU and CPU, operating automatically based on the one with the higher temperature. A comprehensive set of tuning options allow you to tune fan speeds for efficient cooling.

Allows you to set chassis fans to reference either the CPU or GPU temperature to determine rotational speed. Additionally, a smart, automatic calibration routine senses the controllable range of connected fans and allows you to fine-tune speeds for efficient cooling and low noise.

PREMIUM QUALITY AND BEST RELIABILITY

Auto-Extreme Technology

Industry-only 100% Automated Production Process

All ASUS graphics cards are now produced using Auto-Extreme Technology, an industry-exclusive, 100% automated production process that incorporates premium materials to set a new standard of quality. Auto-Extreme Technology ensures consistent graphics card quality as well as improved performance and longevity. Since the introduction of Auto-Extreme technology, reliability has improved by 30%. This new manufacturing process is also environmentally friendly, eliminating harsh chemicals and reducing power consumption by 50%.

Featuring Aura RGB Lighting on both the shroud and backplate, the ROG Poseidon implements a mirror-reflection design concept, giving the illusion of a lighting effect that extends to infinity. The lighting can be customized to display your choice of millions of colors and six different effects. Combined with ASUS Aura Sync RGB LED synchronization technology, you can enjoy a totally personalized gaming system when you pair the ROG Poseidon with an Aura-enabled gaming motherboard.
